Because of the importance of water hummer and it’s big impact in
pumping pipes, an analytical study of water hummer resulting from
the pumping station abruptly stopped working (due to a power
outage on water pipe line that conveys water from groun
d open tank
to three overhead open tanks was conducted, and without means of
protection from water hummer .
maximum and minimum pressure values and the location of each of
them in the network have been identified.
It was found that the pump trip caused a transient state with
negative pressure along the pipe system. The values of maximum
pressure were less than the pressure tube run.
